Cable burn in

Hi all. I’m guessing that what I’m experiencing is pretty normal. But it can’t hurt to get some feedback. I purchased a DMS-650 from Cary Audio which is a DAC/Streamer. Since hifi folks have highly opinionated views on cables, nothing is included with the unit. So when I set it up, I had to scramble and I found the three conductor cable that came with a cheap Sony DVD player. Then I replaced that RCA interconnect with a much better quality Blue Jeans cable. Initially the increase in quality was apparent and obviously worth it. However the sound could be hasrsh on certain recordings. Various tracks had a harshness that wasn’t there before. I’ve been playing internet radio during the day for burn in. Now that harshness has vanished. Sitting down to listen last night, things were actually too warm. Some tracks sounded almost muddy. The sparkle was diminished in an obvious way. I am guessing that once burn is complete the sound will settle happily in the middle somewhere. Is that a reasonable assumption?  I’m also likely going to order power cables and an interconnect from Audio Envy or maybe some other companies to compare. The guy who sold me the Cary Audio gear is not a salesy guy, but he did pretty emphatically recommend some higher quality cables.

@pehare 

what a coincidence. I was just watching a positive review on Mogami. Pro audio makes a lot of sense. I  imagine they have power cables as well. 
Where are you located?

I’m in Apex NC.

Do streamer always play the same song? Or does the compression go up and down with internet bandwidth that is available?

Like varying compression versus time of day?

Qobuz (and I imagine most others) uses lossless compression and high quality streamers use buffering… so the file received will be the same. Obviously, from then on… it is all streamer dependent.

I think variable compression would imply active software on both sides, broadcast and receive. More importantly I think it would imply the compression was not lossless and to make a dent in bandwidth you would need to be lossy. So I doubt it.

I find it hard to believe the claim that "changing a piece of wire" will not produced an improvement.

If it were at all true then all that's need is a thin fuse wire provided it can handle the current. A bit like claiming digital is just 0's and 1's and nothing else matters.

Take speaker cable for example. All frequencies need to be transmitted equally without any timing changes and transients need to arrive at the speaker without change. Hmm, I'm wondering it house mains wire would be suitable. I think not.

Burn in, as a pattern..tends to go:

an initially dirty upper mid range glare and a subtle mono-ish effect,

then down to cleaner stereo but muted/darker/soft,

then slowly back up to cleaner, more evenly balanced dynamic stereo.

 

This, over a 100 hr period of playing a new cable, or component - with line level signals.
